I am currently working towards a PhD in microbial genetics. Before that I spent a bit over a decade working as a programmer, with most of that time spent writing computer games. I have degrees in Mathematics (MMath), Life Sciences (BSc) and Molecular Genetics (MSc).

comment Why only female mammals have well developed mammary glands?
I addressed your first point in the second paragraph. Male investment is high in humans, it is not in mammals in general and the dimorphism in mammaries did not evolve in humans. As to your second point, it's certainly true that males invest in reproduction to similar levels to females but in the individual offspring the investment is higher in the female.

Incidentally, the XY system is not used in all mammals so there is a slight lack of generality here.

I think this answer, while of decent quality, does not actually address the question the OP is asking. This is the mechanics of how there is a difference not the reasons why there is a difference.

comment Why are some fungi poisonous?
@Anixx: I'm not aware of such a claim and would be interested in a source? Even if it is true I am quite certain that those mushrooms will not be poisonous.

comment In males, why it is difficult to control orgasm?
Both men and women can learn to control orgasm for prolonged periods. It is a reasonably common part of BDSM sexual practices to insist that the 'sub' requests permission before orgasming.

comment When writing about past research should I use the species name they employed or the modern version?
I think you're confusing more than one thing here. Campylobacter fetus is the correct, current, internationally recognised name for the species. Like many species, it has been moved to a different genus than it was originally assigned to. The principle of priority applies when the same species has been identified by different researchers.

comment How many humans have been in my lineage? Is it almost the same for every human currently living?
@Joe: It's a model. Any model will be, by it's nature, limited. The limitations are discussed in the paper, as is there potential impacts on the resulting number.

@Joe: It's not my claim. It's the number given in the primary literature source I linked to. Other estimates exist but even then they only push it back to around 8000 years ago, still a small period of time in comparison to the time since the human/chimp split.

Apparently I fail at cut-and-paste, corrected.
